one to many relationship with sqlite and entityframework

I tried to make entity framework latest version (6.1.2) work with Sqlite but i failed, It worked after I downgraded to version 6.0.1 but now I am having a problem with the one to many realtionship mapping

here is the parent and the child class i use:

public   class Teacher
{
    public Teacher()
    {
        Absences = new HashSet<Absence>();
        Students = new HashSet<Student>();
    }

    public long TeacherId { get; set; }

    [Required]
    [StringLength(255)]
    public string FirstName { get; set; }

    //other properties

    public virtual TeacherDetail TeacherDetail { get; set; }
}



public   class TeacherDetail
{
    public TeacherDetail()
    {
        Certifications = new HashSet<Certification>();
        Teachers = new HashSet<Teacher>();
    }

    public long TeacherDetailId { get; set; }

    public long TeacherId { get; set; }

    [StringLength(250)]
    public string Status { get; set; }
   //other properties

    public virtual ICollection<Teacher> Teachers { get; set; }

}

my DbContext class

  public  class DZSchoolEntities : DbContext
{
    public DZSchoolEntities()
        : base("name=DZSchoolDbEntities")
    {
    }

    public virtual DbSet<Absence> Absences { get; set; }
    public virtual DbSet<Certification> Certifications { get; set; }
    public virtual DbSet<Class> Classes { get; set; }
    public virtual DbSet<SchoolDetail> SchoolDetails { get; set;}
    public virtual DbSet<SchoolMember> SchoolMembers { get; set; }
    public virtual DbSet<Student> Students { get; set; }

    public virtual DbSet<TeacherDetail> TeacherDetails { get; set; }
    public virtual DbSet<Teacher> Teachers { get; set; }


    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {

        modelBuilder.Entity<TeacherDetail>()
                    .HasMany<Teacher>(s => s.Teachers)
                    .WithRequired(s => s.TeacherDetail)
                    .HasForeignKey(s => s.TeacherDetailId);
    }
}

in my window loaded event i put this to check:

    void MainView_Loaded(object sender, RoutedEventArgs e)
    {
        var person= new Repo().GetTeachers().Where(m=>m.LastName=="mary").First();
        var teachers = new Repo().GetTeachers(); //it get me the right person
        var detail = person.TeacherDetail; //but it crashes here >_<

    }

I can see the correct attributes of the person object by debuging so everything is working fine with the connection, but I can't navigation through propeties tp obtain the teacher details!

Exception:

***An unhandled exception of type 'System.Data.Entity.Core.EntityCommandExecutionException' occurred in EntityFramework.dll **

Inner Exception:

{"SQL logic error or missing database\r\nno such column: Extent1.TeacherId"}

any suggestions please.
